Just the Facts

"Just the facts, ma'am" -  Sgt. Joe Friday on Dragnet

Private investigation often requires gathering 'the facts' and putting it into a report of some kind.  I was always taught when writing a report to make sure it includes the 4/5 W's.  WHO - WHAT - WHEN - WHERE and sometimes WHY.  Facts are objective. WHY is subjective, and so that is the reason it is only sometimes WHY. 
So just remember Sgt. Joe Friday and the 4 W's and you'll have it covered.
